zoiaims. 01. 101-414) This invention relates to improvements in sprayingapparatus more especially employed to apply a .coloring substance to aportion of the surfaceof an article such as a container or its closure.l v More specifically, the apparatus is adapted for the applicationofvari-colored liquid finger-nail polishes or lacquers to parts of bottlestoppers each shaped to simulate a finger-nail, said part on eachstopper to be sprayed with a liquid colored the same as that to beenclosed in the container so that prospective purchasers may determinethe color or tint of the contents of said container by observance of thenail simulation on the stopper thereof.

An object of the invention is to provide an improved apparatus of simpleand practical construction by means of which a liquid polish or lacquermay be rapidly applied to only a certain defined area of an article suchas a container or its closure. v

The above and other objects will appear more clearly from the followingdetailed description when taken in connection with the acompanyingdrawings which illustrate a preferred embodiment of the inventive idea.In the drawings:

Figure 1 is a fragmentary top plan view of an apparatus constructed inaccordance with the invention.

Figure 2 is a fragmentary side elevation thereof, partly in section.

Figure 3 is an enlarged fragmentary elevation showing a container andits closure or stopper in the position on the turntable of the apparatusin which liquid is to be sprayed onto a D01?- tion of said closure. t

Figure 4 is an enlarged sectional view taken at right angles to Figure3.

Figure 5 is atop plan view of a portion of the turntable showing. a maskin position thereon and ready to receive the closure of a container.Figure 6 is a perspective view of the mask employed, and, l

Figure 7 is an elevation of the container and its closure in an uprightposition after application of a liquid to a portion of i said closure.

One of the specific applications of the invention and that which isshown in the accompanying drawings pertains to the spraying of afinger-nail polish or lacquer onto a defined area of the closure 8 of abottle ii, both of which may be of any design. Preferably, the closure 8is provided with an offset or raised portion [0 of a shape simulatingthat of a fingei nail and it is the purpose of the present invention toapply to the surface of said portion in a polish the color of which isidentical with that to be poured in the container 9.

The apparatus for accomplishing this purpose preferably comprises aturntable in the form of a disc ll mounted for rotation above asupport-f ing frame I2 and having a bearing upon rollers 93. Theturntable H carries a vertically disposed shaft M mounted in bearingswithin the frame l2 and provided with a large gear 55. Meshing with saidgear is a pinion l6 driven from a conventional gear reduction device itto which is connected the prime mover la in the form of an electricmotor. Through the gear reduction l1, the shaft l4 and turntable ii arerotated at the desired speed. Provision is made for supporting aplurality of the containers ii in an inverted position upon theturntable it during the spraying operation. For this purpose there isprovided a supporting ring consisting of a plurality of sections l9 eachof which is individually attached to the upper surface of the turntablel l by means of wing nuts 28 extending through the latter and theextensions 2! formed at the extremities of the inner edges of saidsection. This construction enables the various sections 19 to bedetached from the turntable II whenever it is desired to remove saidsections for the purpose of cleansing the same of any accumulation ofliquid which may adhere thereto during a spraying operation. Each of thesections [9 is provided with a series of openings 22 for receivingaclosure 8 and each opening is reduced at its lower end to form asupporting flange 23 the purpose of which will presently appear. I

In order that liquid directed toward the 010- port the mask in itsnormal inverted position, as

best shown inFigure 4. The mask is provided in the body portion thereofwith an opening 26 shaped similarly to the offset portion of the area Itso that said portion will be exposed through said opening when theclosure 8 is introduced into the mask. Opposed to the opening 26 in themask there is also provided a slot 27 which ex- PATENT oFFica v a tendsthrough the flange 25 and which is adapted to receive an elongated key28 projecting from a surface of the closure 8 diametrically opposite thearea It. When the key 28 is inserted into the slot 27 the area I0 isregistered with the opening 26 in the mask and said key and slotcooperate to prevent any turning movement of the closure 8 relative tothe mask which might otherwise expose a portion of the closure 8 notintended to be sprayed with the liquid.

One or more spraying devices may be arranged about the exterior of theturntable H and disposed so as to direct a liquid such as nail polishonto the areas "I of the various closures as they are rotated relativeto said device. As shown, two spraying devices 29 of any standardconstruction are suitably supported in spaced circumferential relationabout the turntable and the nozzles are so arranged as to direct thespray of liquid onto the exposed portions it of the closures 8 as thelatter are rotated. To prevent excess diffusion of the spray and fumestherefrom, a suction head may be arranged beneath the turntable inopposed relation to each of the sprayers 29 and said heads may beconnected to a conduit 3i leading to; an air suction fan (not shown).

What is claimed is: 1. In combination, a turntable, a sectionalsupporting ring carried bysaid table, with each section of saidrin'gindividually to said turntable;

means to mask a portion of each of said articles, means to spray aliquid onto the unmasked portion of each article, and means to rotatesaid turntable to move said articles relative to said spraying means.

2. In combination, a turntable, a sectional supporting ring carried bysaid table, with each section of said ring having a series of openingstherein for receiving and supporting articles to be sprayed, means todetachahly secure each section of said ring individually to saidturntable, means to mask a portion of each of said articles, means tospray a liquid onto the unmasked portion of each article, means torotate said turntable to move said articles relative to said sprayingmeans, and a suction device opposed to said spraying means.
